This invention relates in general to stoves and has more particular reference to a novel stove construction ada table to stoves emplolying afluid fuel for .Y eating.

he present invention contemplates the provisions of a novel fluid fuel stove in which the fluid container is concealed from view, protected against laccidental damage, insulated from the heatproduced in the use of the stove, and s'lidably supported in the stove to permit its removal for refilling or partial removal for ascertaining the amount of fuel contained in the tank or container.

A primary object of this invention is therefore to provide such a fluid fuel stove with means for slidably receivlng and concealing a fuel-tank or container.

An important object of the invention is the provision of a fuel tank for such a stove which will be insulated from the heat produced in the use of the stove and which may be concealed in a pocket or compartment formed within the burner portion of the stove.

Another important object ofthe invention is the rovision of a fluid'fuel stove having a usual)burner portion and having a pocket or compartment formed in the burner por# tion to slidably receive a. novel fuel tank which will be guided into its proper' operating position and which will closev an end of the recess or compartment.

Other objects and advantages of the invention will be a parent as it is better understood from the ollowing-description which with the accompanying drawings disclose a preferred embodiment thereof.

lFig. 2 is a section taken substantially on the line 2-2 of Fig. 1;

Fig. 3 is a`section taken substantially on the line 3-3 of Fig. 2;

Fig. 4 is a fragmentary plan view of 'the stove shown in Fig. 1 partially exposing the fuel container tank; and

Fi 5 isa side view of the fuel tank show ing t e tank removed from the stove and in a position to be refilled or refueled.

For the (purpose of illustratin the invent1on ,-v the rawmgs show a flui fuel stove havln a body or burner portion fllswhich comprlses a front side 12, a back 13 and side I walls 14 'constructed about a= suitable frame designated generally by the reference number 15, the whole vstructure being supported in any suitable manner or as shown m, Fig. 1

by legs 16. It will be understood that the burner portion 11 forms an enclosure about a pluralty controll by handles 17 projecting from the front of the stove, the burners being adapted to'direct heat to a plurality of grids or plates 18 supported in a usual manner in a top frame member 19 of the burner' portion 11 for 'supporting cooking utensils which are used to hold food being cooked. v

A plate 20 underlies each of the rear grids 18, 1n the form illustrated in Fig.I 3, which guide the heating Y gases thereto and mamtam the gases in spaced relation to the underlying fuel tank *or container.

An aperture 21 is provided in one of the wallsl 14 and adapted to communicate with a of burners,'not shown, which areket or compartment 2 2 formed within the urner portion 11 for 'a'purpose which will be more fully described presently. The pocket 22 is formed by a plate having a top horizontal portion 23 and vertical sides 24 and 25 cooperating with one of the sides 14 and the back 13 of the burner portion and being held in place by bolt and nut assemblies 26 passmg through a depending marginal portion 27 at the inner side of the top frame 19 and a vertical flan e 28 extendin about the front end and a side of the poc et 22 above the horizontal top 23; the top 23 and the sides 24 and 25 of this plate separate the pocket 22 from the remainder of the burner portion 11 and provide means for protecting and concealing a fueltank 29 which will be more fully described hereinafter. To supplement the heat baling means provided by the top 23 and sides 24 and 25, an angular plate havin a top 31 and asidev32 is mounted in spaced re ation with the top 23 andthe side 25 respectively of the heat baling means. by any. suitable means such as spot welded depressed lugs, shown at 33 in Figs.. 2 and 3, and proof the heat produced in the use of the stove.

The sidel 24 of the pocket 22 is provided with a marginal flange 35 extending the height of the side 24 to facilitate mounting the heat baflling means at the back ofthe 4stove and to strengthen and stiffen this c\on struction about the pocket 22; the pocket 22 communicates at its bottom with a fuel reservoir 36v formed by dishing or otherwise suitably forming a plate 37 supported by a flange 38 from the bottom of the aperture 21and secured thereto by bolt and nut assemblies 39, and supported at its opposite end or side by a' strip 41 having vertical sides or legs 42 and formed to provide a supportlng sad- 'dle 43 for supporting the dished plate 37',

the strip 41 being secured to the frame 15 at the lower ends of the vertical members 42 by bolt and nut assemblies 44 securing flanges 45 of the strip to the frame 15.

The reservoir 36 is adapted to supply fuel through a suitable pipe connection 46 securedy in the bottom ofthe plate 37' by jam nuts 47 arranged at opposite sides of the plate 37 to the burners of the stove, the fuel being supplied to the reservoir 36 from the tank or container 29 which is slidably positionable in the pocket 22 as will now be described.

A suitable angle or supportingbar 48 is mounted at each side ofthe pocket 22 by means of a face or a leg of the member 48 engaging in a horizontal slot or recess 49, as shown in Fig. 1, provided at opposite sides of the aperture 21 and secured at this. end by means of' a bolt and nut assembly 51 holding each supporting bar 48 to a vertical flange 52 formed in the side 14 at opposite sides of the aperture 21. The supporting bars 48 provide inclined tracks or guide members for the tank 29 and are secured at their ends opposite the aperture 21 to the vertical portions 42 of the strip 41 bymeans of bolt and nut assemblies 53 to provide means for sliding the tank 29 through the aperture 21 into the pocket `22 above the fuel reservoir to supply fuel to the stove.

To accomplish such sliding of the tank 29 in the pocket 22, the tank is provided with an inclined peripheral flange 54 shown more particularly in Figs. 2 and 5 having substantially the same degree of inclina-tion as the tracks or guides 48 so that the flange 54 being aligned with the horizontal slots 49 may be inserted in the aperture -21, and the flange sliding upon the tracks or guides 48 may be pushed into the pocket until a valve stem 56 of a valve 57 slidably mounted in a threaded refilling or inlet connection or boss 58 arranged at thebottom of the tank rides upon and depresses a yielding, platform or lug 59 in the lreservoir 36 to lift or actuate the stem 56 whereby to supply fuel to the reservoir from the tank. This platform or lug 59 is provided with a downwardly inclined portion 61 and a substantially horizontal portion 62 which may be slightly inclined from the horizontal for smoother engagement with and more rapid opening of the valve if so desired. The horizontal portion 62 is secured to the reservoir 37 at its front end and projects rearwardly therefrom, terminating in the downwardly inclined portion 61, which normally terminates a short distance from the bottom of the reservoir so that the member 59, being constructed of resilient metal, is capable of a certain amount of yielding or spring in its coaction with the valve stem 56. It will be manifest that this construction also permits the ready removal of the tank 29 from the pocket 22 without binding between the valve stem and the platform or lug 59 or without damaging the valve stem.

The tank 29 is adapted to close an end of the pocket communicating with the aperture 21 in order to conceal the tank within the pocket, providing means for the ready insertion or removal of the tank supported by the tracks or' guides 48. To this end the tank is provided at an end thereof with a plate 6R suitably secured as by welding or soldering to the top of the tank and an angle 64 having a vertical leg 65 suitably secured to an end of the tank 29 and a substantially horizontal leg 66 projecting therefrom. The plate 63 and the horizontal leg 66 are respectively adapted to be secured by bolt4 and nut assemblies 67 and 68 to horizontal legs 69 and 71 of angles 72 and 73 having Vertical legs suitably secured to a plate or door 74.

This plate or door 74 secured at one end of the tank 29 as already described, is provided at its top and bottom with marginal ledges or flanges 75 and 76 which seat against the side 14 above and below the aperture 21 effecting a neat closure for the aperture. A handle or finger opening 77 is formed substantially centrally of the door or plate 74 to facilitate withdrawing the tank from the pocket 22.

This door or plate 74 extends vertically above the top of the tank 29 and provides a support as shown' in Fig. 5 forl o ne end of the tank 29 when it has been removed from the pocket and inverted for the purpose of refilling or refueling the tank. The other' end of the tank 29 is adapted to be supported by a handle 78 pivotally secured to the top of the tank as at 79 and adapted to swing outwardly about the pivot 79 to provide with the plate 74 a substantially level support for the tank and to facilitate carrying or transporting the tankduring or after refilling ,it.

A feature of the present invention resides in so concealing the fuel tank 22 as above de'- scribed and arranging it so that it may be readily removed from its place of concealhas ment for the purpose of refilling or partially or the proper repositioning of the tank in the operatmg position and by sliding the tank on the tracks or guides 48 in the pocket 22 and providing the tank with a suitable fuel y indicating device'or gauge 81 of any usual or preferred construction near the outer end of the tank 29 so that it will be necessary to. draw the tank only a comparatively short f distance out of the pocket to read the gauge 81. In the present embodiment of the inven` tion this gauge 81 is shown in Fig. 4 mounted in the top of the tank 29 adjacentthe plate 63.

2o Thus it will be understood that a fuel tank has been provided for a fluid fuel stove whichl is concealed within the stove body, insulated from the heat of the stove, protected against r accidental injury, the tank being adapted to be positioned within the stove body by l. inserting it throu h an aperture which the tank closes, and sli ing the tank along guiding tracks into an insulated pocket to the proper operating position. This construction, it will 3o be apparent, eliminates the unsightly mount- Y ing of the tank at an end of the stove within full view as was heretofore common in the art, obviates the necessity of painstaking adjust-ment of the tankso that the tank valve will be in operative position, and does away with the tendency to spill fuel as the tank is removed from or replaced in operating position, thereby considerably improving the appearance and the utility of stoves employing fluid fuel for heating.
